I am getting a bug building Cygwin on latest SVN :-
llvm[1]: Compiling Process.cpp for Debug build
In file included from /home/ang/git/workbench/lib/System/Process.cpp:29:
/home/ang/git/workbench/lib/System/Unix/Process.inc: In function 'unsigned
int g
etColumns(int)':
/home/ang/git/workbench/lib/System/Unix/Process.inc:209: error: aggregate
'winsi
ze ws' has incomplete type and cannot be defined
/home/ang/git/workbench/lib/System/Unix/Process.inc:210: error:
'TIOCGWINSZ'
was
not declared in this scope
make[1]: *** [/home/ang/build/workbench/lib/System/Debug/Process.o] Error 1
make[1]: Leaving directory `/home/ang/build/workbench/lib/System'
make: *** [all] Error 1
Having IOCTL.H does not seem to be a strict enough test for struct
winsize'es presence.
#ifdef HAVE_SYS_IOCTL_H
// Try to determine the width of the terminal.
struct winsize ws;
if (ioctl(FileID, TIOCGWINSZ, &ws) == 0)
Columns = ws.ws_col;
#endif
I could not see any changes in Process.cpp's SVN that could have caused
this.
Anyone got a clue ?

Doug,
It is declared in <sys/termios.h>

Can you fix it, please? Thanks, Jay.
